|---|---|
| Name | Defines the name of the modeling object. |
| Label | Specifies a unique numerical identifier for the modeling object. |
| Properties | |
| Type | TYPE field in the NLARCL bulk entry.Lets you specify the arc-length method. |
| Minimum Arc-Length Adjustment Ratio | MINALR field in the NLARCL bulk entry.Lets you specify the minimum allowable arc-length adjustment ratio between increments for the adaptive arc-length method. |
| Maximum Arc-Length Adjustment Ratio | MAXALR field in the NLARCL bulk entry.Lets you specify the maximum allowable arc-length adjustment ratio between increments for the adaptive arc-length method. |
| Bound on Load Increment/Arc-Length Ratio | MAXR field in the NLARCL bulk entry.Lets you specify the overall upper and lower bounds on the load increment /arc-length in the subcase. |
| Scale Factor for Loading | SCALE field in the NLARCL bulk entry.Scale factor for controlling the loading contribution in the arc-length constraint. |
| Desired Number of Iterations | DESITER field in the NLARCL bulk entry.Lets you specify the desired number of iterations for convergence to use for the adaptive arc-length adjustment. |
